Pehea e koho ai i ka hydroxypropyl methylcellulose mai ka paʻa wai

ʻO ka paʻa wai mai ka hydroxypropyl methylcellulose kekahi o nā waiwai nui o ka hydroxypropyl methylcellulose.ʻO nā mea e like me ke ea wela, ka mahana a me ka wikiwiki o ka makani e hoʻopili i ka nui o ka volatilization o ka wai i loko o ka mortar sima a me nā huahana gypsum.No laila, i nā kau like ʻole, aia kekahi mau ʻokoʻa i ka hopena paʻa wai o nā huahana me ka nui o ka hydroxypropyl methylcellulose i hoʻohui ʻia.

ʻO ka mea maʻamau, ʻoi aku ka kiʻekiʻe o ka viscosity o ka hydroxypropyl methylcellulose, ʻoi aku ka maikaʻi o ka hopena o ka mālama ʻana i ka wai, akā e hoʻemi ʻia ka hopena o ka viscosity i ka paʻa ʻana o ka wai i ka wā e ʻoi aku ka viscosity ma mua o 100,000 mpa.s.No ka hydroxypropyl methylcellulose me ka viscosity ʻoi aku ma mua o 100,000, pono e hoʻonui i ka nui o ka hydroxypropyl methylcellulose e hoʻonui nui i ka nui o ka mālama ʻana i ka wai.

I ke kūkulu kikoʻī, hiki ke hoʻoponopono ʻia ka hopena paʻa wai o ka slurry ma ka hoʻonui a hoʻemi ʻana i ka nui o ka hydroxypropyl methylcellulose.Hiki i nā huahana Hydroxypropyl methylcellulose series ke hoʻoponopono pono i ka pilikia o ka paʻa ʻana o ka wai ma lalo o ke kiʻekiʻe kiʻekiʻe.I nā kau wela kiʻekiʻe, ʻoi aku hoʻi ma nā wahi wela a maloʻo a me ka hana ʻana i ka ʻāpana lahilahi ma ka ʻaoʻao o ka lā, koi ʻia ka hydroxypropyl methylcellulose kiʻekiʻe e hoʻomaikaʻi i ka paʻa ʻana o ka wai o ka slurry.

ʻO ka hydroxypropyl methylcellulose kiʻekiʻe he kūlike maikaʻi loa.Hoʻokaʻawale ʻia kona mau pūʻulu methoxyl a me hydroxypropoxyl ma ke kaulahao mole cellulose.Hiki iā ia ke hoʻomaikaʻi i nā ʻātoma oxygen ma nā paʻa hydroxyl a me ether.ʻO ka hiki i ka hui wai ke hana i nā paʻa hydrogen e hoʻohuli i ka wai manuahi i wai i hoʻopaʻa ʻia, a laila e hoʻomalu maikaʻi i ka hoʻoheheʻe ʻana o ka wai ma muli o ke anuanu kiʻekiʻe a loaʻa ka paʻa wai kiʻekiʻe.

Hiki i ka hydroxypropyl methylcellulose kiʻekiʻe kiʻekiʻe ke hoʻopuehu i loko o ka pahu sima a me nā huahana gypsum, e hoʻopili i nā mea paʻa paʻa a pau, a hana i kahi kiʻi ʻoniʻoni, a e hoʻokuʻu mālie ʻia ka makū o ke kumu no ka manawa lōʻihi.Loaʻa ka hopena hydration me ka mea gelling inorganic, a laila e hōʻoia i ka ikaika paʻa a me ka ikaika compressive o ka mea.No laila, i ke kūkulu ʻana i ke kauwela kiʻekiʻe, i mea e hoʻokō ai i ka hopena paʻa wai, pono ia e hoʻohui i nā huahana hydroxypropyl methylcellulose kiʻekiʻe i ka nui e like me ke ʻano, inā ʻaʻole, lawa ʻole ka hydration, hoʻemi ʻia ka ikaika, a hiki mai ka haki ʻana. i ka maloʻo nui.ʻO nā pilikia maikaʻi e like me ka hollowing, hollowing a me ka hāʻule ʻana e hoʻonui i ka paʻakikī o ke kūkulu ʻana no nā limahana.Ke hāʻule nei ka mahana, hiki ke hoʻemi iki ʻia ka nui o ka hydroxypropyl methylcellulose i hoʻohui ʻia, a hiki ke hoʻokō ʻia ka hopena paʻa wai like.
